(scm_chmod, scm_stat, scm_truncate_file: likewise.
* fports.c (scm_fdes_to_port), ports.c (scm_void_port),
filesys.c (scm_opendir):
restore defer interrupts while the port is constructed.
* (scm_setvbuf): if mode is _IOFBF and size is not supplied,
derive buffer size from fdes or use a default.
(scm_fdes_to_port): use setvbuf instead of creating the buffers
directly.
* filesys.c (scm_fsync): use SCM_FDES.
* filesys.c (scm_fcntl): get fdes from fport.
(set_element, get_element): likewise.
* filesys.c (scm_open): adjust port_mode for O_APPEND and O_CREAT.
ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
just protecting errno. some may need to be put back.
* * ports.c (scm_drain_input): new procedure.
ports.h: prototype.
* fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY,
pre_read, pre_write): removed.
(local_fputc, local_fputs, local_ffwrite): use write, not stdio.
(scm_standard_stream_to_port): change first arg from FILE * to
int fdes.
(local_fflush): flush fdes, not FILE *.
* fports.h (SCM_NOFTELL): removed.
* genio.c, ports.c: don't include filesys.h.
* genio.c (scm_getc): don't use scm_internal_select if FPORT.
do it in fports.c:local_fgetc.
* genio.c: don't use SCM_SYSCALL when calling ptob procedures.
do it where it's needed in the port smobs.
* filesys.c (scm_input_waiting_p): moved to fports.c, stdio
buffer support removed. take SCM arg, not FILE *.
* filesys.h: prototype moved too.
* fports.c (scm_fdes_to_port): new procedure.
(local_fgetc): use read not fgetc.
(local_fclose): use close, not fclose.
(local_fgets): use read, not fgets
* fports.h: prototype for scm_fdes_to_port.
* fports.h (scm_fport): new struct.

#include fcntl.h
* ports.h (struct scm_port_table): change stream from SCM to void *.
* ports.c (scm_add_to_port_table): check for memory allocation error.
(scm_prinport): remove MSDOS hair.
(scm_void_port): set stream to 0 instead of SCM_BOOL_F.
(scm_close_port): don't throw errors: do it in fports.c.
error messages, not the uninitialized string `str'. Love that
typechecking.
* strop.c (scm_substring_move_x): New function, which can handle
arbitrary overlapping substrings.
(substring-move-left!, substring-move-right!): These are
now just synonyms for substring-move!.
* strop.h (scm_substring_move_x): New prototype.
(scm_substring_move_left_x, scm_substring_move_right_x):
#define these as synonyms for scm_substring_move_x.
functions; capitalize the first letter of each word in the
argument string, and downcase the rest.
(scm_string_ci_to_symbol): string->symbol, such that the same
symbol is returned for any argument where the only difference
between strings is in capitalization.
(scm_string_upcase, scm_string_downcase): non-destructive
versions.
* strop.c (scm_substring_move_left_x, scm_substring_move_right_x):
changed to use memmove.
* strop.c (scm_i_index): removed the pos arguments (it's only
called twice, and each time it's SCM_ARG1, SCM_ARG2, SCM_ARG3,
SCM_ARG4).
* strop.h: fixed prototypes.
* * strop.c (scm_substring_move_left_x, scm_substring_move_right_x):
changed to have 5 required args, rather than 2 required, and 3 required
rest args. Also modified to allow str1 & str2 to overlap.
(scm_substring_fill_x): changed to 4 args, rather than 2 args and
2 required rest args.
Libguile should not be exporting random little strings.
* numbers.h (s_bignum): Extern declaration removed.
More const changes from Ken Raeburn.
* numbers.c (scm_s_bignum, fx): Now const.
(scm_logtab, scm_ilentab, s_adjbig): Now static and const.
* numbers.h (scm_s_bignum): Update declaration.
* eval.c (bodycheck): Argument WHAT now points to const.
* snarf.h (SCM_SYNTAX): Name is const.
* eval.c (scm_i_let): Make this globally visible, to avoid dynamic
linking crashes on NetBSD. (Thanks to Ken Raeburn.)
non-zero value if X is finite. (From ISO C 9x standard.)
(scm_inexact_to_exact): Bugfix: Don't pass NaNs to scm_dbl2big.
(Thanks to Jon Trowbridge and Greg Harvey.)
(scm_system_module_env_p): Assume root environment is no lookup
closure is found.
* modules.c, modules.h, eval.c, eval.h (scm_env_top_level,
scm_top_level_env, scm_system_module_env_p): Moved to modules.c.
